Identify the wrong statement from the following
Options
- AThe product formed when (–)–2–Methylbutan–1–ol is heated with Conc. HCl is (+)–1–Chloro–2–methylbutane with Re
- BVinyl halides do not undergo nucleophilic substitution reaction easily
- CS_N1 reaction of Alkyl halides is favoured by the presence of bulky substituents, protic solvents and the reac
- DS_N2 reaction of optically active halides are accompanied by Retention of configuration
Correct answer
D. S_N2 reaction of optically active halides are accompanied by Retention of configuration
Step-by-step solution
Option (A): The reaction of (–)–2–methylbutan–1–ol with conc. HCl involves the cleavage of the C–O bond at C1. The bonds attached to the chiral center at C2 are not broken, so the spatial arrangement (configuration) is retained. This statement is correct. Option (B): Vinyl halides are highly unreactive towards nucleophilic substitution because the C–X bond acquires partial double bond character due to resonance, and the sp^2 hybridized carbon is less susceptible to nucleophilic attack. This statement is correct. Op
